Prevent Opposite Operative's Larceny

Operation: P.O.O.L. is the fourth episode of Season 4 of Codename: Kids Next Door. It first aired on December 10, 2004 on Cartoon Network.

Information[]

Summary[]

Numbuh 4's new pool opens a portal to an alternate version of the KND Universe where their counterparts known as the DNK (Destructively Nefarious Kids) are evil. The kids do all the adults job's whereas the adults sit around and play video games. While swimming in the pool, Lizzie is captured by an evil opposite of herself, Eizzil Enived (Lizzie's name backwards), and Nigel follows the captor back to her home universe.

Plot[]

The episode begins with Numbuh 4 answering the door to Numbuh's 2, 3, and 5, who excitedly run through the house claiming 'Pool Party!'. When Numbuh 4 follows them - in a disappointed manner - his father asks him about the new pool, to which Numbuh 4 responds to by reminding him that he can't swim, only for his father to then leave the house to his second job.

As Numbuh 4 is complaining about not going to the beach, Numbuh 1 appears and apologizes for being late due to 'negatronic readings' and the fact that his girlfriend, Lizzie, couldn't decide on what to wear to the pool.

As Lizzie is about to leave and change her swimming costume, her reflection in the pool comes to life and drags her under the water, with Nigel immediately diving in to save her, once he reaches the bottom, he seemingly spots Lizzie and chases after her, only to then come across a tree house similar to Sector V's, but with 'DNK' instead of KND and confronts Lizzie, but Nigel quickly realizes that this is not Lizzie and is flung into the tree house.

Later, Nigel awakens to discover himself in chains and struggles to get free, when 'Lizzie' confronts him and questions him about how he knew she wasn't his girlfriend, to which Nigel responds by noting her eyes and claiming that the real Lizzie is 'not a jerk'. He then demands to know where Lizzie is and is greeted by the real Lizzie falling out of a doorway, who then runs to him.

After Lizzie questions him on where they are, Nigel suggests that 'Lizzie's' ex-boyfriend should explain, after a reluctant statement about the 'Supreme Leader', a different Nigel appears and the real Nigel deduces that the other Nigel is Negative Numbuh 1 and that Numbuh 4's pool opened a portal to an upside-down world.

Negative Numbuh 1 briefly explains what their world is like and declares that they are the 'Destructively Nefarious Kids' (DNK). After a brief verbal scuffle, Eizzil pulls out a S.P.A.T.T.L.E. and is about to torture Nigel and Lizzie, when the Little Traitor Dudes For Children's Defense bust in and save Nigel and Lizzie. During the scuffle, Lizzie hits Negative Numbuh 1 with the S.P.A.T.T.L.E and knocks out a tooth, before escaping.

Once Negative Numbuh 1 and Eizzil recover, they are contacted by the Supreme Leader and are ordered to continue their plan, lest they be sent to the broccoli mines. Meanwhile, while running with the Little Traitor Dudes For Children's Defense, Nigel and Lizzle witness the atrocities of this new world with kids doing constant work and the adults being the lazy ones.

The group enters the LTDFCD 'mansion' (Which is really an RV) and call out to their 'Daddy', who Nigel and Lizzie are initially frightened of due to the silhouette and believe him to be Father, only for a normal looking man to come out and console his children. Nigel asks what happened to this world and Daddy explains that it was the DNK who caused this in the first place. Apparently, they despise other children so much that they forced the children to do all the work while their parents sat around doing nothing and demanding bigger allowances. The LTDFCD tell them that they need to get back to their world, before it's too late, immediately afterwards, the 'mansion' is under attack by DNK members. The LTDFCD help Nigel and Lizzie escape before battling the DNK.

After escaping from the RV, Nigel and Lizzie are confronted by Negative Numbuh 86 and are about to be arrested, but Nigel tells Lizzie to follow his lead and pretends to be Negative Numbuh 1 and acts like he is angry about being 'interrupted while working for the Supreme Leader'. After some hesitation, Negative Numbuh 86 lets them go and orders her squad to stand down.

After losing sight of them, Nigel and Lizzie run back to the pool and are about to jump back in, but then are presumably attacked by something before they emerge from the water, Nigel is revealed to have a missing tooth before the transmission cuts off.

Once the transmission continues, 'Nigel' attempts to push Numbuh 4 into the water before the others put a stop to it, knowing that Wally can't swim. 'Nigel' and Wally head back to the tree house after some weird moments and not long after, Hoagie, Abby and Kuki are dragged underwater, with their negative selves arriving in their place.

In the treehouse, Negative Numbuh 1, Eizzil, and Wally (under the impression that they are the real versions), are taking apart one of Hoagie's machines and then the others appear, but Wally then realizes that his teammates are not those who he'd been working with after looking in Negative Numbuh 3's eyes, and Negative Numbuh 3 offers Numbuh Four a deal. At that point, he refused to help the DNK because he is loyal to the KND and would never betray his teammates. Disgusted by them, Wally punches the evil girl away and then proceeds to fight the rest of the DNK single-handedly, as they are heard screaming in the treehouse. He later convinced Eizzil to look at the error of her ways and make amends to stop Negative Numbuh 4's plans to take over the positive world.

Meanwhile, in the other world, the positive version of the kids are confronted by Negative Numbuh 4, the main leader of the DNK and the one responsible for the current outcome of the other world. After making fun of Negative Numbuh 4's goatee, the supreme leader declares that the KND will fight until one is left standing to be his bodyguard. However, they refuse to fight and are sentenced to the broccoli mines. While being transported, Nigel attempts to convince Negative Numbuh 86 to switch sides, the scene cuts away before we are shown the result.

Meanwhile, Negative Numbuh 4 is preparing to jump into the pool and enter the real world, but his DNK operatives surface, all battered and beaten by Wally, who gives himself the courage to jump into the pool and enter the upside-down world to confront his opposite self.

While Negative Numbuh 4 points out how he is outnumbered by his troops and calling him an idiot for coming there, Wally declares his other self to be a coward, hiding behind his troops and pointing out how his other self is hiding behind bullies, something the real Numbuh 4 wouldn't do.

Just as Negative Numbuh 4's troops are about to fire, Negative Numbuh 86 comes in with the positive KND, including Lizzie, and gives a short speech about how she is sick of their current lifestyle and wishes to be her own person, which inspires the other DNK members to put down their weapons and proclaim what they want to do with their lives (this also results in the dark, cloudy skies becoming clear and showing the world's light).

Negative Numbuh 4 attempts to order his group around, only for Negative Numbuh 2 to joke about his cowardice and goatee, which everyone laughs at, except the real Numbuh 2, who doesn't find the joke funny.

Negative Numbuh 4 is determined to prove his bravery, declaring to Wally that he'll take his world for himself. He then jumps into the real world to conquer it. As the KND and their counterparts make amends, Negative Numbuh 1 questions Wally on why he let his opposite self into the real world. Wally sinisterly responds he has a feeling Negative Numbuh 4 won't like it there. Negative Numbuh 4 reaches the other world, gloating at how he'll take over only for Eizzil to literally kick him back into their world. Negative Numbuh 4 is captured and then sent to the mines.

The DNK then claim to make their world a better place along with the LTDFCD and Eizzil. The KND then leave the other world and return home, with Negative Numbuh 86 ordering the pool to be drained, closing the portal and leaving to change their world.

During the end credits, Sector V are playing in the pool, which has now become a sand pit, with Wally singing his 'buried in the sand' song, the song lasts into the night, with the other members leaving one by one. After it is night, Wally continues to be in the sand and sings his song.

Trivia[]

  • In the credits, the pool now has sand in it, and Numbuh 4 sings his "Buried in the Sand" song about it.
  • Everything is completely opposite of the real world, both of the organizations, technology and the characters' personalities. For example, the DNK are evil, while the LTDFCD and Daddy are good. Their names also seem to be reversed in spelling (Lizzie's counterpart's name is Eizzil).
  • This episode indirectly reveals that Numbuh 3 actually likes Numbuh 4. At one point in the episode, Negative Numbuh 3 says to Numbuh 4 she doesn't like him. Since Negative Numbuh 3 is the complete opposite of Numbuh 3, it indirectly means that Numbuh 3 likes Numbuh 4.
  • It is unknown how Numbuh 4 defeated the Negative Sector V, but they appear in worse shape than their positive counterparts, despite the latter being tortured with electricity.
  • This is the last season and episode to air in 2004.
  • Negative Numbuh 4 breaks the fourth wall by mentioning Adult Swim, a late-night programming block on Cartoon Network.
  • Since the LTDFCD are good, this means that they may be Negative Sector Z who were once truly evil.
  • When the positive Sector V minus Numbuh 4 are captured in the Negaverse, Negative Nunbuh 4 says the line "Who wants to battle for a Get out of Jail Free Card". Coincidentally, Get out of Jail Free Card is one of the elements on the Monopoly board game, in which each set of the game has 2 of it located on Chance and Community Chest card piles.
  • There are certain elements in the Negaverse that hint towards future episodes:
    • Eizzil and Negative Numbuh 1 being exes foreshadows the events of Operation: G.I.R.L.F.R.I.E.N.D., where Lizzie would break up with Nigel.
    • The Negative versions of Sector V with opposite personalities are a hint to the positive ones temporarily taking on similar ones in Operation: C.A.R.A.M.E.L..
    • This episode also foreshadows the DCFDTL and Father's true origins in Operation: Z.E.R.O.:
      • If you notice the alternate universe's acronyms, they are said to be traitors. The DCFDTL are also traitors.
      • Daddy's appearance is very similar to Father's appearance without his silhouette suit.
  • The Teen Ninjas (including Cree Lincoln and Chad Dickson) would be implied to be good as well in the negative world (assuming that they're evil in the positive world).
  • A sequel to episode was adapted into a mission in the Operation B.E.S.T. game.

Series continuity[]

Cultural references[]

  • This episode is somewhat based off the Star Trek episode entitled "Mirror, Mirror", where the crew of the Enterprise encounter their own evil twins. The Evil Spock had a goatee like Negative Numbuh 4's, which denotes evil twin status.
  • This episode is similar to the The Adventures of Jimmy Neutron: Boy Genius PC game, Jimmy Neutron vs. Jimmy Negatron where Jimmy Neutron gets trapped in his evil counterpart's dimension and Jimmy Negatron invades his.

Goofs[]

  • When Eizzil appears as Lizzie's reflection in the pool, she has the flower tucked in on her left side. This changes when she grabs Lizzie, and the flower is on her right side.
  • Numbuh 1 was not standing on any markings on the ground before Eizzil clicks on her remote.
  • Despite the LTDFCD entering with an explosion, no hole appears on the wall when they swing in.
  • The distance between the platform and the wall vary signifanctly.
  • The manhole that Numbuh 1 and Lizzie escape out of disappears once Nega 86 appears.
  • The DNK guards behind Nega 86 are missing during her close-up.
  • The Moon changes place several times during scenes.
  • Nega 1 and Numbuh 3 switched places in the pool between part 1 and part 2.
  • Nega 1 starts pushing Numbuh 4 into the pool while they are next to the house door, but have somehow moved to another side of the pool in the next shot.
  • When Negative Numbuh 2, 3 and 5 appear in the treehouse, they enter from inside the central power core, even though that room was on the other side of the hallway and where Nega 1 and Eizzil just came from.
  • The wheel Nega 1 and Eizzil is moving disappears from the hallway.
  • Negative Sector V has disappeared from the pool when positive Numbuh 4 appears.
  • Negative Numbuh 2 is somehow wearing his actual hat with "-2" on the front when he emerges beaten up in the pool, despite wearing positive Numbuh 2's in the positive world.
  • Even though it was just night and the Moon was visible in the sky, it somehow turns to day with sunshine as soon as the clouds clear.
  • When Negative Numbuh 2 tells his joke about Negative Numbuh 4's goatee, Numbuh 2 can be seen laughing along with everyone else. However in the next scene, Numbuh 2 is clearly not amused by the joke.
  • When Negative Numbuh 4 is jumping off of the diving board to go to the positive world, it doesn't show Positive Numbuh 4 on the diving board when he was there less than 2 seconds before he jumped.
  • It isn't explained why Eizzil kicked Negative Numbuh 4 out of the real world, in the last scene, the real Lizzie is bruised from her time in the DNK treehouse, with Eizzil having no marks on her. Eizzil isn't seen emerging from the water when Wally confronts his evil self and thus has no idea about Negative Numbuh 4's cowardice and downfall. Eizzil is also not wet, unlike everyone else who went through the pool.
    • Though it can be argued that Eizzil was able to figure Negative Numbuh 4 out after seeing what Numbuh 4 is like. Also, she wasn't wet due to staying in the positive universe per Numbuh 4's request and quickly becoming his friend, which was evident after she told Negative Numbuh 4 to "get out of [her] friend's world".
